【摘要】 运用精确的解析推导方法对圆TE11模微波窗的额定平均功率公式做了修正,给出了圆柱盒型窗中介质窗片温升的具体计算方法,并结合实际问题对圆柱盒型窗用于传输高功率连续波时的功率容限和鬼模振荡的特殊危害性以及排除方法进行了详细的讨论。研究结果表明:在L波段,只要排除工作频带内的鬼模,普通圆柱盒型窗用于传输120～150kW的连续波不成问题,并且可以得到14%左右的相对带宽。更多还原

【Abstract】 The formula for calculating the threshold of average transmitting power of cylindrical TE11 mode window is revised by accurate deduction.A practical method for calculating the temperature increment of the dielectric disk in cylindrical box type window is given. Meanwhile, a typical cylindrical box type window is calculated and used as an example to discuss the power capacity, the special harmfulness and elimination of ghost mode resonance when the window is used to transmit high power CW.It is showed that, in L band, general cylindrical box type windows may be used to transmit 120～150kW CW and the possible relative bandwidth is 14% or so, in the case of elimination of the ghost mode.更多还原
